RAYMOND COMPANY OF NEW'YOBK, N. Y., A CORPORATION OF NEW YORK snwme MACHINE LIGHT ARR NGEMEN Application filed .Tu1y28, 1928; serial No, 295,972..

The present invention relates to electric light attachments for sewing machines and has for its object the provision of a lighting fixture unusually simple in construction, ef-

5 fective in operation and inexpensive to manu- I f acture. My invention is particularlyadapted for use with high speed sewing machines of the portable type and when so usedhas certainspecial advantages hereinafter stated.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a. better understanding of theinvention, how- 15 ever, and the advantages possessed by it, reference shouldbe'had to the accompanying drawing and descriptivematter in which I have illustrated and described a preferred embodiment of'the inventiom Of the drawing I V Fig. 1 is a rear elevation of my invention; and

Fig.2 is an end elevation with portions of the light broken away.

In the preferred form of my invention shown inthe drawing, the sewing machine comprises a base member upon which is detachably secured the frame casting of' the machine. The latter comprises a bed B, a

standard G rising from one end ofthebed portion and a horizontal arm D supported by the standard C and terminating at its free end in the head E The top surface of the bed B serves as the cloth surface'or work support of the machine. The, usual hook actuating mechanism is contained within the bed B and driven from a hook shaft B through a pulley F The arm D and head E contain the actuating mechanism for reciprocating a presser bar and a needle bar E, into the lower. end of which a needle H is inserted; The various operating. mechanisms arepreferablydriven by an electric motor J containedlwithin the bed B and connected to the. pulley F" by a. belt F The motor projectsthrough an aperturein the topsurface of the bed B. The sewing machine illustrated. is aportable high. speed: machine such as is described and claimed in the pending application of R. K: Hohma-nn, Serial No. 242,368, filed'December 24', 1927;

The electric light fixture of my invention is particularly advantageous in machines of this type, and in'carryingoutmy invention I provide a bracket M consisting of a flat plate Mf secured to'thestandard (l on the side opposite the operator and at a point thereon adjacent the junction with the arm 1) by threaded bolts M The platehas; an upper I U-shapedportion M inclined away from the standard C and plate M and arranged to receive a central portion of an incandescent lamp socket. The plate M" is also provided with an integral laterally projecting arm M having its outer end formed with a clip M for purposes hereinafter described A screw threaded bolt N is mounted in an'opening L. PLUMLEYQOF BROOKLYN, new yoamnssienon T0 nnnnnnrcx osnnn 7 in the free end oftheU-shaped bracket por tion -M with its threaded portion N arranged in a threaded opening in the other leg adjacent the standard C. 'Thebolt head is provided with a kerf N into which ascrewdriver or other tool maybe inserted for ad- 7 justing thebol-t N to loosenor tightenthe bracket portion M about the lamp) The electric lamp of my invention is mounted in the bracket heretofore described at the rear of the standard C'and arranged in such a manner that the longitudinal axis ofthe lamp passes through the lower part of the needle H when the latter is infits raised position andintersects the portion ofthe bed'B serving as the work} support of the'ma j a I I 85 chine. p The electric lamp consists of asubstantially cylindrical lamp socket O and a bellshaped reflector P, each'of which is'provided with tapered end portions 0 and 1P, re'- spectively, adjacent to and connected to each other; A lamp bulb Q mounted in the taperedportion ofthe socket O'with' its-outer end positioned in the reflector. The tapered portion of the reflector is provided witha series of openings R spaced about its circumference and'providing ventilation for'the lamp bulb Q. As shown in Fig. 1, the lamp is held in an inclined position" with respect to the standard G by inserting the reduced portioniof the socket 0 into the U shaped bracket" portion M as shown in Fig. 2. The electric lamp is held in the bracket by the bolt N securing the legs of the U-shaped portion together. A cord S containing a pair of electric conductors is inserted in the upper end of the socket O and held adjacent the standard C by the clip M As shown in F ig; 1, the lamp is held in such a position and the reflector and bulb so proportioned and arranged that the light rays are focussed on the nee le eye and work where illumination is most necessary.

My invention has other advantages than those heretofore stated. The operator being seated at the side of the machine opposite the lamp will not be subjected to any glare from the light due to the arrangement of the reflector P. Any light rays passing out of the lamp ventilating openings R will be prevented from reaching the operator by the standard 0.

The described arrangement of the lamp is particularly advantageous on sewing machines required to be frequently shifted by the user as it leaves the major portion of the horizontal arm free to be grasped by the user in moving the machine. The capacity for such manual operations is particularly important in machines usually requiring manual shifting from an inoperative position to another position in which they are capable of operation, such as, for example, in a light weight portable machine to permit the re moval of the same from or restoration to a carrying case or its transporting where desired, and also with a sewing machine of the drop head type in raising the same to or lowering itrfrom its operative position. The lamp being entirely within the reflector P prevents any contact by the hand or arm of the lifter with the bulb Q. The location of the bracket and lamp on the standard C,

rather than. on the reduced portion of the arm D or head E, also reduces the vibration of the lamp andmateriallyincreases the life of the bulb used therein. Both the bracket and lamp are very simple in construction and may be manufactured at a relatively low cost. The lamp socketand reflector are preferably spun together during the assembly of the parts. The fixture may be installed with slight modification of the existing sew.- ing machine to which it is applied. The arrangement of the conductor cord in the bracket clip prevents the possibility of the cord contacting with or becoming entangled in any of the moving parts of the machine.

ile in accordance with the provisions of the statutes, the best form of embodiment of my inventlon now known to me, it will be apparent to those skilled in the art made in the form of the apparatus disclosed without departing from the-spirit of my invention as set forth-in-the appended claims I have illustrated and described that changes may be and that in some cases certain features of my invention may be used to advantage without a corresponding use of other features. 7

Having now described my invention what I claim as new and desire to secure by Letters Patent, is: V
